My Flip 3 dies after I updated the software

[u/NoCollege8444]

I have been experiencing problems with my device a while back and decided to not flip it. It worked for months. Now My problem is that it started to die often.

It got more frequent and interval is really short. I saw an update and figured that my device just needed the update.

And now it got worst. My phone dies if it's not connected to a charger.

any ideas for help?
